NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Routes

小心地使用 Match(Rails 3 已实现)

Rails 3 提供了 match 方法供我们自定义 routes,然而我们要小心使用它以避免“跨站脚本攻击”(XSS Attack)。比如像这样的 routes:

注:(r3 代表 Rails 3,r4 代表 Rails 4)

Ruby Debugger

Most of the time simple output statements using warn, raise, or a logger will help you find your issue. But sometimes you need the big guns, and that means ruby-debug.

Ruby-Debug

The ruby-debug package has had some rocky times during the transition from Ruby 1.8.7 to 1.9.2 and beyond. But now, finally, the debugger is reliable and usable.
